Evaluation of ocular involvement in patients with Hansen's disease.

Hansen's disease (HD) belongs to the group of neglected diseases and can cause physical deformities and disabilities, in addition to leading to social discrimination. Ocular involvement in HD is estimated at 70-75% worldwide. About 10-50% suffer from severe ocular symptoms and loss of vision occurs in approximately 5% of cases.

Primary cutaneous amelanotic melanoma and gastrointestinal stromal tumor in synchronous evolution.

Gastrointestinal stromal tumor is rare digestive tract mesenchymal tumor, most often in the wall of the stomach. It is a benign neoplasm, but it can become malignant if not treated. We report a case of gastrointestinal stromal tumor that was discovered after abdominal ultrasonography during staging of a patient with primary cutaneous amelanotic melanoma.

Dermoscopy of black skin: A cross-sectional study of clinical and dermoscopic features of melanocytic lesions in individuals with type V/VI skin compared to those with type I/II skin.

Background: The identification of "normal" dermoscopic patterns of acquired melanocytic nevi provides better diagnostic accuracy for melanoma in people with black skin.

Objective: We sought to describe melanocytic lesions (numbers and anatomic distributions) in skin types V and VI compared with skin types I and II, according to the Fitzpatrick classification. We sought to identify differences in dermoscopic findings in acquired melanocytic nevi (global pattern, pigment and color distribution) between the groups.

Case report: Dermoscopic and histological aspects of skin graft and perigraft hyperpigmentation in acral location.

Little is known about the use of dermoscopy in skin grafting. We describe the case of a patient with skin grafting and surrounding pigmentation on acral region. The dermoscopic findings were similar to those of benign acral lesions (lattice-like pattern) and reactive pigmentations (fine striae).
